the Cretaceous extinction happened and
what disappeared.
What is 65 million years ago scientists
think that an asteroid hit the Earth
which caused a climate change and the
dinosaurs disappeared? After the
dinosaurs died out, many new
mammals began appearing.
Species Change over Time
100
The relative age of a fossil tells you
a. whether one fossil is older or younger than another fossil
b. exactly when a fossil was formed
c. the amount of radioactivity in a fossil
d. how long the fossilized organism was alive on Earth
What is A, whether one fossil is older or
younger than another fossil?
Species Change over Time
200
Lamarck proposed that species evolve because:
A. they adapt to their surroundings over time.
B. they can pass on traits acquired during their lifetimes to
their offspring.
C. they overproduce and a variety of species come from
each offspring.
D. natural laws decide when they should change.
What is B, they can pass on traits
acquired during their lifetimes to
their offspring?

Species Change over Time
400
According to Lamarck, could the parents of
the tortoise from Abingdon Island be born
with a short neck?
What is yes, they could have stretched their
necks during their lives and then passed on
that trait to their offspring?
Species Change over Time
500
This is how variation and adaptation may
have led to the development of longnecked tortoises on Abingdon Island.
Species Change over Time
500 Answer Slide
• The offspring of the ancestors of present-day
tortoises on Abingdon island differed from
each other in small ways.
• One of these variations was likely neck
length. The tortoises competed with one
another for leaves.
• The better adapted tortoises, with long necks,
survived and reproduced at a higher rate.
• Therefore, long-necked tortoises became
more widespread.
Evidence for Evolution
100

used in different ways. This is evidence that supports
the theory of evolution by_________.
a. artificial selection
b. natural selection
c. acquired characteristics
d. similarity of structures
What is similarity of structures?
Evidence for Evolution

c. bacterium and human
d. human and tree
What is a, tree and flower?
Evidence for Evolution

in the diagram to the
right is an example of a
vestigial organ.
What is the whale leg is a structure that
was fully developed in whale ancestors;
now it has become reduced and unused
in modern whales?
Evidence for Evolution
400
